You spend a third of your life sleeping – but if you play your cards right, you can spend a lot more time than that in bed… you know, doing sex.

Come to think of it, why restrict yourself to the bedroom? You can have just as much grown-up fun in the backseat of your car… or in a hotel room… in an elevator… or a public park… even a gritty dive bar bathroom or– well, you get the picture.

There are as many ways and places to have sex as there are days in the year. So unless you’re a bona fide Casanova, you’d better get cracking on this nowhere-near comprehensive sex bucket list, like, yesterday.
